Tent frame assembly

Abstract

A tent frame assembly includes a leg unit, a plurality of link units, and a plurality of first and second struts. The leg unit includes a plurality of upright posts respectively having top connection elements, and a plurality of sleeve units. Each link unit includes an upper foldable link with two first link sections and a first pivot unit between the first link sections, and a lower foldable link with two second link sections and a second pivot unit between the second link sections. Each first strut has one end pivoted to a corresponding sleeve unit and the other end pivoted to one of the first link sections. Each second strut has one end pivoted to a corresponding top connection element and the other end pivoted to one of the second link sections.

1 . A tent frame assembly for mounting a canopy thereon, comprising: 
 a leg unit including a plurality of spaced-apart upright posts respectively having first top connection elements, and a plurality of sleeve units sleeved slidably and respectively on said upright posts below said first top connection elements;    a plurality of link units, each of which includes two upper and lower foldable links disposed between an adjacent pair of said upright posts, said upper foldable link including two first link sections respectively pivoted to said first top connection elements of said upright posts of the adjacent pair, and a first pivot unit connected between said first link sections, said lower foldable link including two second link sections respectively pivoted to said sleeve units of said upright posts of the adjacent pair, and a second pivot unit connected between said second link sections;    a plurality of first struts, each of which has one end pivoted to a corresponding one of said sleeve units and the other end pivoted to one of said first link sections; and    a plurality of second struts, each of which has one end pivoted to a corresponding one of said first top connection elements and the other end pivoted to one of said second link sections.    
   
   
       2 . The tent frame assembly as claimed in  claim 1 , wherein said first pivot unit has a U-shaped first channel, and two spaced apart pins which pass through said first channel to pivot respectively said first link sections, said second pivot unit having a U-shaped second channel, and two spaced apart pins which pass through said second channel to pivot respectively said second link sections.  
   
   
       3 . The tent frame assembly as claimed in  claim 2 , wherein said first channel opens upwardly, and said second channel opening downwardly.  
   
   
       4 . The tent frame assembly as claimed in  claim 1 , further comprising a top support frame connected pivotally to said leg unit.  
   
   
       5 . The tent frame assembly as claimed in  claim 4 , wherein each of said upright posts further includes a second top connection element which is angularly spaced apart from one of said first top connection elements, said top support frame including a topmost connecting unit, a plurality of first support rods pivoted respectively to said second top connection elements of said upright posts, a plurality of second support rods pivoted respectively to said first support rods and extending toward each other and pivoted to said topmost connecting unit, and a plurality of third struts each having one end pivoted to a corresponding one of said sleeve units and the other end pivoted to a corresponding one of said first support rods.
